Domain from a Table of Quadratics

Based on this table of values of a quadratic function, what is the VERTEX?

• (-4, 0)

• cannot be determined

• (-1, -9)

• (0, -8)

What is the range of this quadratic function?

y = x² - 8

• y > -8

• y < -8

• x = all real numbers

• y = all real numbers

Using the graph of y = -1.5x² + 12x - 23 shown here, what are the values of x when y = -5?

• x = 4

• x = 2, 6

• x = 3.2, 4.8

• cannot be determined on the graph

What are the other names for the "solution(s)" to a quadratic equation?

**Select all that apply!**

• root(s)

• x-intercept(s)

• zero(s)

• y-intercept(s)

Given a quadratic equation in standard form, y = ax² + bx + c, how do you find the equation for the AXIS OF SYMMETRY?

If a quadratic equation has 2 solutions, they will be equal distance from the axis of symmetry.

• TRUE

• FALSE

Which graph will be the most vertically stretched compared to the quadratic parent function?

• g(x) = -x² + 9

• g(x) = 5x² + 1

• g(x) = 0.2x² - 11

• g(x) = -3x² - 6

If the "bx" term is missing in a standard form quadratic, the equation for the axis of symmetry is x = 0.

(example: y = -2x² - 10)

• TRUE

• FALSE

If the zeros of a quadratic function are (1, 0) and (9, 0), what is the equation of the axis of symmetry?

• x = 1

• x = 9

• y = 0

• x = 5

• cannot be determined from this information

If there is only one zero of a quadratic function located at (3.5, 0), what is the equation of the axis of symmetry?

• x = 7

• x = 3.5

• y = 0

• x = 0

• cannot be determined from this information
